Until it's full.

Until it's full.

But if we are right at the surface of where the water is now, is the glass already full?

Okay.

That's what you mean.

Has time already timed out?

That's right.

Has already ticked.

And we're just experiencing it.

This has been explored in several science fiction stories.

For example, Ted Chiang's excellent story called Story of Your Life, which became adapted into the movie Arrival that starred Amy Adams and Jeremy Renner.

That's right.

That's right.

Oh, so, so, so don't, don't, don't spoil it for those people who haven't read it yet.

It's worth reading once, but, but yes, exactly.

That's right.

So this is sometimes referred to as what's called block time or a block universe where there are four dimensions of space and time and it's already filled.

It's a block that's already filled and we just happen to be moving through it.

And because of our physical limitations, we can only move it in one direction.

But that is only one possible solution to the mathematical equations.
